You want to stay within the same quality range, but no, the jumpers must not match the speaker cable. Your logic does make sense to a point. Here come the rebuttals........
Jumpers vs bi-wire
Question for the experts: If I run straight cables to my speakers and then use cable jumpers to replace the metal connectors that came with the speakers (mine are set up with a high and low post for the speaker connections), do the cable jumpers need to be the same brand/model as the main cable in order to achieve the same benefits/attributes of the main cable. It seems the answer would be yes, but so few cable makers seem to make jumpers. Am I missing something (would not be the first time). My limited knowledge of such suggests to me that to get the same benefits/attributes to both high and low binding posts, I'd have to bi-wire (or shotgun). Your thoughts would be greatly appreciated.
